Kenneth Graunke b0629e6894 i965: Implement rasterizer discard via SOL unless required for queries. ... We currently use CL_INVOCATION_COUNT for the GL_PRIMITIVES_GENERATED query, which involves passing all primitives to the clipper. When rasterizer discard is enabled, we program the clipper in REJECT_ALL mode, rather than using the SOL stage's "Rendering Disable" feature. See commit f09b91f782 for an explanation of why we implement GL_PRIMITIVES_GENERATED this way. Apparently the SOL stage's "Rendering Disable" feature is a lot faster than having the clipper reject all primitives. It's safe to use when no GL_PRIMITIVES_GENERATED query is active, as we don't care about CL_INVOCATION_COUNT incrementing. This patch makes us use SO_RENDERING_DISABLE when no query is active, but continues falling back to the clipper in REJECT_ALL mode when the queries are enabled. It brings back the perf_debug for the clipper case (which I removed in commit 1f9445ff57, thinking it wasn't useful). Improves performance in Gl32GSCloth by 84.8303% +/- 2.07132% (n = 10) on my Broadwell GT2 laptop.
